Blankets, Quilts or comforters, like other clothing and bedding items, need regular cleaning. For Quilts, comforters and blankets are used extensively, it is recommended that you wash them around once a month to keep dust, germs, microbes and soil from building up. Most blankets are washing machine safe under the right settings, but as it is a volume item, it needs to be underloaded to make it free moving inside the machine to have a good clean.
But before washing any comforter, it is advisable to check the wash care tag/ instructions. A number of comforters may be for dry clean only. Dry cleaning may be a better option than washing by machine or hand. Some comforters can’t hold up against a wash cycle, even on the delicate setting, and could lose their shape. Dry cleaning gently removes stains without the risk of damage.
Dry cleaning uses chemical solvents instead of water soluble or liquid chemicals to clean bedding. Laundry detergents along with long exposure to water during washing can strip natural coating of the fibers and hence of the fabric. This coating keeps the comforter soft and fluffy. Without this coating, comforter will become flat.
Some materials, like wool, silk, or cashmere, should never be soaked in water. Water may damage the material. Also, placing these fabrics in a washing machine could distort their shape or cause dark colors to fade.
Unlike using a washing machine, dry cleaning your comforter effectively removes dirt without damaging it.
